  • Publication number: 20240139726
    Abstract: According to the disclosure, a target analyte detection cartridge includes a sample chamber into which sample is inserted, a metering chamber connected to the sample chamber to meter a predetermined amount of sample, a mixing chamber connected to the metering chamber to receive a magnet bead, and a waste chamber connected to the metering chamber. The metering chamber has one side connected to each of the sample chamber and the mixing chamber and another side connected to the waste chamber. A first pneumatic flow path to which pneumatic pressure is provided is connected to a waste flow path that joins the other side of the metering chamber to connect the metering chamber and the waster chamber.

  • Patent number: 9785735
    Abstract: A system and method perform global routing during integrated circuit fabrication. The method includes performing a design change in a portion of an integrated circuit design using a processor, determining whether the design change requires rerouting, and requesting a global routing lock based on determining that the design change requires the rerouting. The method also includes a router providing control of the global routing lock to one of two or more of the threads that request the global routing lock, and performing global routing for all of the two or more of the threads in parallel. A physical implementation of the integrated circuit design is obtained.

  • Publication number: 20160015379
    Abstract: Rotator cuff tears (complete and partial) are surgically repaired without needing more dermal access than percutaneous punctures. The surgeon is afforded a range of options for where to place a second tunnel in the bone, and selection by the surgeon of a desired bone bridge size is provided in advance of tunnel construction. Also, stitching in rotator cuff surgery can be accomplished without the need for suture anchors or added cost of secondary suture passers. Multiple stitch configurations including X-patterns are possible with combinations of preloaded loops and or sutures passed simultaneously through tissue and bone. Fixation is achieved without the use of suture anchors, buttons or other rigid implants.

  • Patent number: 9127565
    Abstract: An apparatus includes a metal shell (200, 300) surrounding a body (230, 330) that is made of a ceramic matrix composite (CMC) material (231) The metal shell defines a space (250) adapted to contain the body and includes at least one protrusion (220) adapted to contact the body. A compliant porous element (240) is adapted to fit in the space between the metal shell and the body. A preload spring (260, 360) is provided in an urging orientation with the body wherein the preload spring is positioned against a first region (333) of the body and is adapted to urge the body toward one of the protrusions positioned against a second region (335) generally opposite the first region, and also to preload the compliant porous element. One of the protrusions may be a hard stop, and in the preload, one of the protrusions may be loaded.
